Question

Drag and drop the descriptions in the box that correctly classifies the angle pairs.

You may use multiple responses in the boxes.

Answer 1

a) ∠CEA and ∠DEB are reflections of each other across point E, the intersection point of lines CD and AB. They are vertical angles.

b) ∠AED and ∠BED together form a straight line, so are a linear pair. That means they are adjacent and supplementary.
